Historically, fatty acids were not considered to be major substrates for mitochondrial respiration, but there is a growing appreciation of the importance of fatty acid respiration in developing seedlings and mature plants. These apparently are converted by enzymes during the maturing process to fatty acids and glycerol, which then form glycerides. Lipogenesis is the process of synthesizing these fats.
