15 Hydrophobic interactions may occur between the R groups of which of the following amino acids? a. Amino acids are grouped according to what their side chains are like
This fact has important implications for proteins’ tertiary structure (see the Proteins 2 module for a discussion of tertiary structure).. These are serine (Ser), threonine (Thr), cysteine (Cys), asparagine (Asn), glutamine (Gln), and tyrosine (Tyr)
Hydrophobic and Polar Amino Acids [2]
Amino acids are grouped according to what their side chains are like. side chains are glycine (Gly), alanine (Ala), valine (Val), leucine (Leu), isoleucine (Ile), proline (Pro), phenylalanine (Phe), methionine (Met), and tryptophan (Trp)
This fact has important implications for proteins’ tertiary structure (see the Proteins 2 module for a discussion of tertiary structure).. These are serine (Ser), threonine (Thr), cysteine (Cys), asparagine (Asn), glutamine (Gln), and tyrosine (Tyr)
Characteristics of the 20 Amino Acids: Hydrophobic, Hydrophilic, Polar and Charged [3]
When considering polarity, some amino acids are straightforward to define as polar, while in other cases, we may encounter disagreements. For example, serine (Ser, S), threonine (Thr, T), and tyrosine (Tyr, Y) are polar since they carry a hydroxylic (-OH) group
Tyrosine is also involved in metal binding in many enzymatic sites. Asparagine (Asn, N) and glutamine (Gln, Q) also belong to this group and may donate or accept a hydrogen bond
When both groups are protonated, the side chain has a charge of +1. Within protein molecules, the pKa may be modulated by the environment so that the side chain may give away a proton and become neutral or accept a proton, becoming charged

This incredible array of functions derives from a startlingly simple code that specifies a hugely diverse set of structures.. In fact, each gene in cellular DNA contains the code for a unique protein structure
The folded shape, or conformation, depends directly on the linear amino acid sequence of the protein.. The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain (see below)
Hydrophobic Interaction: A Promising Driving Force for the Biomedical Applications of Nucleic Acids [6]
Hydrophobic Interaction: A Promising Driving Force for the Biomedical Applications of Nucleic Acids. The comprehensive understanding and proper use of supramolecular interactions have become critical for the development of functional materials, and so is the biomedical application of nucleic acids (NAs)
However, hydrophobic interaction shows some unique properties, such as high tunability for application interest, minimal effect on NA functionality, and sensitivity to external stimuli. Therefore, the widespread use of hydrophobic interaction has promoted the evolution of NA‐based biomaterials in higher‐order self‐assembly, drug/gene‐delivery systems, and stimuli‐responsive systems
1) The hydrophobic interaction of NA itself comes from the accumulation of base‐stacking forces, by which the NAs with certain base compositions and chain lengths show properties similar to thermal‐responsive polymers. 2) In conjugation with hydrophobic molecules, NA amphiphiles show interesting self‐assembly structures with unique properties in many new biosensing and therapeutic strategies
Hydrogen Bonding [7]
A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. Intermolecular forces (IMFs) occur between molecules
Hydrogen bonds are are generally stronger than ordinary dipole-dipole and dispersion forces, but weaker than true covalent and ionic bonds.. If you plot the boiling points of the compounds of the group 14 elements with hydrogen, you find that the boiling points increase as you go down the group.
If you repeat this exercise with the compounds of the elements in groups 15, 16, and 17 with hydrogen, something odd happens.. Although the same reasoning applies for group 4 of the periodic table, the boiling point of the compound of hydrogen with the first element in each group is abnormally high
hydrophobic bonding [8]
Hydrophobic bonds in proteins arise as a consequence of the interaction of their hydrophobic (i.e., “water-disliking”) amino acids with the polar solvent, water. The hydrophobic amino acids are gly, ala, val, leu, ile, met, pro, phe, trp (see amino acid structures for reference)
To understand the formation of hydrophobic bonds, familiarity with the energetics that drive the packing of solvent H2O molecules into liquid lattices is required. Note: in the JSmol visualizations below only single planes of water shell molecules are shown, for ease of visulaization.
Thermodynamic considerations tell us that the formation of these lattices arise as H2O molecules attempt to optimize the number of energetically favorable H-bonds. Consider what happens, then, if hydrophobic, amino acid sidechains “poke” into the aqueous solvent

Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective; they may serve in transport, storage, or membranes; or they may be toxins or enzymes
Their structures, like their functions, vary greatly. They are all, however, polymers of alpha amino acids, arranged in a linear sequence and connected together by covalent bonds.
Complete MCAT Amino Acids Proteins Guide [10]
Amino Acids are the Building Blocks of Proteins probably lurks right behind Mitochondria is the Powerhouse of the Cell in your subconscious. As a topic on the MCAT, amino acids are incredibly high yield
If you wrack your brain a bit more, you probably remember that amino acids can be classified based on their different properties. Due to how foundational proteins and amino acids are as a topic, knowledge of them is essential for MCAT success
At the end, we’ll break down how to read research passages pertaining to the topic as they will appear on the MCAT. Plus, premier instructor Phil Hawkins has created a video masterclass to accompany the article.
Biology Online Dictionary [11]
/ˈhaɪdrəʊ.fɪlɪk/ Definition: Capable of interacting with water through hydrogen bonding. What does a hydrophile (or hydrophilic molecule) mean? If a molecule is “water-loving”, it is known as ‘hydrophile’ (noun) that possesses a hydrophilic nature
The degree or extent to which a molecule or surface attracts water is known as the ‘hydrophilicity‘ of that molecule. Some of the most common examples of hydrophilic substances are sugar, salt, starch, and cellulose.
Etymology: from Greek hydros, meaning “water” and philia, meaning “friendship”. ‘Like dissolves like’ theory governs the fact that hydrophilic substances tend to readily dissolve in water or polar solvents while hydrophobic substances are poorly soluble in water or polar solvents.
Hydrophobic interactions control the self-assembly of DNA and cellulose [12]
Despite the ever-increasing attention on research on DNA and cellulose (exemplified, for instance, by the works of Kostag et al. (Reference Kostag, Jedvert, Achtel, Heinze and El Seoud2018, Reference Kostag, Gericke, Heinze and El Seoud2019), Budtova and Navard (Reference Budtova and Navard2016), Chen et al
(Reference Podgornik, Aksoyoglu, Yasar, Svenšek and Parsegian2016), Travers and Muskhelishvili (Reference Travers and Muskhelishvili2015), Frank-Kamenetskii and Prakash (Reference Frank-Kamenetskii and Prakash2014) or Peters and Maher (Reference Peters and Maher2010) dictated by the genetic role and the role as a raw material in achieving a more sustainable society, respectively, aspects related to basic mechanisms continue to be controversial. In particular, the recent attempts to understand the balance between hydrophilic and hydrophobic properties are noted (Glasser et al., Reference Glasser, Atalla, Blackwell, Malcolm Brown, Burchard, French, Klemm and Nishiyama2012; Vologodskii and Frank-Kamenetskii, Reference VologodskII and Frank-Kamenetskii2018; Feng et al., Reference Feng, Sosa, Mårtensson, Jiang, Tong, Dorfman, Takahashi, Lincoln, Bustamante, Westerlund and Nordén2019).
As will be discussed in this review, an understanding relates to the balance between hydrogen bonding and hydrophobic interactions. Recent research has demonstrated that often the hydrophobic interactions have been underestimated
