Acetyl group known as paracetamol), and acetylsalicylic acid (better known as aspirin). The introduction of an acetyl group into a molecule is called acetylation. In biological organisms, acetyl groups are commonly transferred from acetyl-CoA to other organic molecules. Acetyl-CoA is an intermediate both in the biological synthesis and in the breakdown of many organic molecules. Acetyl-CoA is also created during the second stage of cellular respiration, the Krebs Cycle, by the action of pyruvate dehydrogenase on pyruvic acid. Histones and other proteins are often modified by acetylation. For example, on the DNA level, histone acetylation by acetyltransferases (HATs) causes an expansion of
Cupboard love is formed when the mother satisfies her infant's basic needs. However, they argue on how these needs are met. Psychoanalysts debate that a baby can only be gratified through physiological means (feeding, security, etc.). Whereas, behaviorists contend that conditioning is more probable. Regardless, each theory suggests that attachment is a form of “cupboard love” as the mother is only loved because she satisfies her infant's needs.
