What is NOT a function of proteins?
What is NOT a function of proteins?
Conversion of glucose to energy is primarily carried out by enzymes, which are proteins. However, proteins don't directly convert glucose to energy; that's the role of enzymes.
What type of side chains do glycine and alanine have?
What type of side chains do glycine and alanine have?
Glycine and alanine are amino acids with simple, non-polar side chains made up of only carbon and hydrogen atoms. These chains are very basic and don't interact strongly with water.
What type of side chain does tyrosine have?
What type of side chain does tyrosine have?
Tyrosine has a large, aromatic ring structure in its side chain. Aromatic rings are cyclic structures with alternating single and double bonds, giving them unique properties.
